Windows 7: After KB3004394, no IE, no MS updates

I installed the updates from 12/9 including KB3004394 and immediately lost Internet Explorer along with any subsequent MS updates. To make matters worse, some of my administrator ability has apparently been lost and I can view installed updates but not remove any of them. A system restore to an earlier date has not helped. The MS fixit is dead as well. Is there anything else I can try other than bringing it to a shop for repair?

What AV are you using?Please disable real-time scanning/protection and reboot

If the notification has disappeared, re-enable real-time scanning and reboot again

If the notification is still present, first check whether the real-time scanning is still switched off If so, then re-enable it and post the result. If it's turned itself back on then tell me or try again using a different disable option.

The AV I am using is MSE. I have tried disabling/re-enabling the real time protection; it remains disabled until I re-enable it and remains enabled unless I disable. Trying what you suggested hasn't helped.

I have had no internet connection since this problem developed, although the wireless network connection status shows that it is connected. I also tried plugging in the cable but have the same result.

If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)

Series of Unfortunate Events - From KB3004394 to lost product keysOkay, so I'm in a very, for lack of a better word, "messy" situation right now. I'll try to make this easy to follow.
So, for a little while now, my father's computer has said it wasn't running Genuine Windows. When he finally mentioned it to me last month, I was afraid I had inadvertently...

General Discussion

Question about KB3004394I have seen lots of web pages about fix KB3004394 released last December. It sounds like a very bad, buggy fix. Well, I now see a KB3004394, published 2/10/2015 waiting to be installed on my PC. I can very few references to it. There's a description from MS. I don't have a copy of the...

Windows Updates & Activation

Windows suddenly not genuine (KB3004394 ??)After installing a bunch of updates (among which the infamous KB3004394) early this week, I started getting the 'windows not genuine' message (my copy is 100% legal). I run the KB3024777 update which is supposed to fix things, but I'm still getting the 'windows not genuine' message. Any ideas?

Warning - KB3004394 corrupts system filesIn today's set of Windows 7 updates there is the above KB that corrupts system files - at least in my system. I immediately noticed that my Magnifier .exe was dead and it also mucked around with my Rocket Dock. When you run the updates, you better deselect or hide that one.
